Otitis externa is a common condition of the ear. It is manifested as narrowing of the lumen owing to the edematous swelling of the ear canal lining. Perichondritis may occur independently or as a complication of the otitis externa. We report a case of perichondritis after using a topical ear drop. Changing the medication provides immediate resolution of the condition.

Necrotizing otitis externa (NOE), also called malignant otitis externa, corresponds to osteomyelitis of the skull base [1]. NOE occurs primarily in diabetic elderly patients with a male preponderance [2]. Typically due to pseudomonas aeruginosa, NOE begins as a soft tissue infection of the external auditory canal (EAC) and spreads via the fissures of Santorini and the tympanomastoid suture to i...

Introduction: Cerumen is known as ear wax, produced regularly by cerumen and lipid secretary glands. Regarding the effect of Mazandaran province's humid weather on the prevalence of pathogenic microorganisms, this study was performed to determine the bacterial flora of the ear in patients with acute otitis externa and its comparison with healthy subjects. Materials and Methods: In this case-...

Background: Essential oils (EOs) are recommended by some veterinarians to treat otitis externa in pets, but data about their efficacy in scientific literature are very scant. Methods: Nine commercial EOs, from roman chamomile (Anthemis nobilis L.), star anise (Illicium verum), lavender (Lavandula hybrida), litsea (Litsea cubeba (Lour.) Pers.), basil (Ocimum basilicum L.), oregano (Origanum vulg...

INTRODUCTION Malassezia species are commensals of normal skin microbial flora of humans and animals. These may become pathogenic under certain conditions such as those associated with atopic dermatitis or otitis externa in dogs. MATERIAL AND METHODS Isolates of Malassezia pachydermatis were obtained from 27 dogs with healthy external ears and 32 dogs with otitis externa. Isolates were charact...

Background:To compare the microbiology of Cerumen bacterial flora in acute otitis externa patients and healthy individuals. Methods: In this comparative study a total of 120 participants were included, consisting of 50 patients of acute otitis externa patients and 70 healthy participants. Healthy cases without any medical problems but with cerumen in the ear canal were enrolled ascontrol group....

felt that visualization of the tympanic membrane was important for diagnosing otitis externa. This survey demonstrates that although there is widespread knowledge that aural toilet, antibiotics and steroid ear drops are appropriate treatment for otitis externa, there are a number of general practitioners who appear to have difficulty in making this diagnosis. The pattern of our clinic referrals...

Pseudoaneurysm of the internal carotid artery (ICA) is a rare complication of head and neck infections. To date, three cases of petrous ICA pseudoaneurysm have been described as a complication of otogenic infection, including only one secondary to malignant otitis externa. We present here the first case of cervical ICA pseudoaneurysm as a complication of malignant otitis externa, and stress the...

BACKGROUND Canine otitis externa, an inflammation of the external ear canal, can be maintained and worsened by bacterial or fungal infections. For topical treatment, combinations of anti-inflammatory and antimicrobial ingredients are mainly used. HYPOTHESIS/OBJECTIVES This study was conducted to elucidate the in vitro activity of polymyxin B and miconazole against clinical bacterial isolates ...

BACKGROUND Otitis externa is a common clinical problem in general practice and yet there are remarkably few data available on the demographic characteristics of patients with this condition and the approaches used by general practitioners (GPs) in the United Kingdom (UK) to manage it. AIM To define the descriptive epidemiology of otitis externa in the general population, to describe the first...
